The master communications device and the slave device interact as a single device provided by the master communications device/slave device configuration. The slave device serves as an extension to the master communications device providing a larger interface to the operator.

Description

BACKGROUND
• 1. Field of Invention
• The invention relates to communications devices, and more specifically to intelligently operating multiple communications devices within an interactive communications system environment.
• 2. Related Art
• Typically, a communications system includes a single device that allows an operator to operate and/or control the communications system. For example, the operator when interacting with the communications system is limited to the features and resources available to the operator by the device.
• Operation of the communications system in the manner described above limits the operator to the size and the capabilities of the conventional device when interacting with the communications system. The typical device may be adequate for the operator when performing certain tasks with the communications system such as placing a telephone call. However, the operator may also wish to operate the communications system for other tasks that require additional features and resources that the device cannot provide such as simultaneously browsing the internet and/or reading emails. The operator of the communications system will be limited to the conventional device and cannot add to the features and resources of the conventional device, such as increase the size of the display for the conventional device to provide an example, in operating the communications system.
• Thus, there is a need to add additional features and resources to the conventional device when required by the operator while allowing the operator to return to the conventional device when the operator no longer requires additional features and resources. Further aspects and advantages of the invention will become apparent from the detailed description that follows.

A First Exemplary Master Communications Device/Slave Device Configuration
• FIG. 2 illustrates a block diagram of a masterslave communications system200 according to an exemplary embodiment of the invention. Amaster communications device202 may be integrated with aslave device204 to form the masterslave communications system200, where theslave device204 may be representative of a plurality ofslave devices204.
• Themaster communications device202 may be, for example, a mobile telephone, a portable computing device, other computing devices such as a personal computer, a laptop, or a desktop computer, a computer peripheral such as a printer, a portable audio and/or a video player, a payment system, a ticketing writing system such as a parking ticketing system, a bus ticketing system, a train ticketing system or an entrance ticketing system to provide some examples, or in a ticket reading system, a toy, a game, a poster, packaging, an advertising material, a product inventory checking system and/or any other suitable electronic device that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention.
• Themaster communications device202 may also include a touch-screen display, an alphanumeric keypad, a microphone, a mouse, a speaker, a liquid crystal display (LCD), a light emitting diode (LED), a projector, a plasma television, data light processing (DLP) projector, liquid crystal on silicon (LCoS), digital direct drive image light amplifier (D-ILA), cathode ray tube (CRT), and/or any other suitable user interface that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, or any combination thereof.
• Theslave device204 may include a touch-screen display, an alphanumeric keypad, a microphone, a mouse, a speaker, and/or a liquid crystal display (LCD), a light emitting diode (LED), a projector, a plasma television, data light processing (DLP) projector, liquid crystal on silicon (LCoS), digital direct drive image light amplifier (D-ILA), cathode ray tube (CRT) and/or any other suitable device that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, or any combination thereof.
• The masterslave communications system200 enables the seamless and automated attachment of theslave device204 to themaster communications device202. The operator may require additional functions and resources that themaster communications device202 alone cannot provide. In such a case, themaster communications device202 may in a seamless and automated fashion engage theslave device204 where theslave device204 and themaster communications device202 provide an interactive communications system to the operator.
• For example, the operator may enter a conference room with amaster communications device202 that is a personal laptop. The operator may require a larger display to properly display the information currently displayed on themaster communications device202. Themaster communications device202 may engage theslave device204 that is a projector located in the conference room to display the information of themaster communications device202 on the wall of the conference room. Such an interaction between themaster communications device202 and theslave device204 may be seamless and automated.
• When requested to perform a particular service by the operator, themaster communications device202 takes an inventory of the features and resources that are necessary for providing the particular service, and compares the inventory to those resources contained solely in themaster communications device202. If the features and resources contained in themaster communications device202 are sufficient to perform the service for the operator, then themaster communications device202 performs the service. However, if the features and resources of themaster communications device202 are not be sufficient to perform the service for the operator, then themaster communications device202 may engage theslave device204 to provide additional features and resources that are necessary or desired to perform the service.
• Themaster communications device202 may operate in a discovery mode and theslave device204 may operate in an advertise mode. Themaster communications device202 enters into discovery mode to search for slave devices, such as theslave device204, to expand the features and resources of themaster communications device202 to include the features and resources of theslave device204. Theslave device204 enters into advertise mode to notify themaster communications device202 that theslave device204 is ready to engage with themaster communications device202. Either themaster communications device202 and/or theslave device204 may initiate the engagement between the devices. The operator may also set both themaster communications device202 and theslave device204 into the discovery and advertise modes, respectively. In an embodiment, themaster communications device202 has no inherent resources of its own, and therefore is always operating in discovery mode once a service request is received. Likewise in a further embodiment, theslave device204 is always in an advertise mode; such a slave device may be a conference projector, for example.
• In an embodiment, themaster communications device202 and theslave device204 may engage with each other in the discovery and/or advertisement modes using a sensor, as discussed in greater detail below. As would be appreciated those skilled in the relevant art(s) without departing from the spirit and scope of the present invention, a sensor receives a signal and responds to the received signal. The sensor may be located on themaster communications device202 and/or theslave device204. As an example, the sensor may be a near field communications device (NFC) or other wireless device to effect the sensor operations.
• As discussed above, the operator in operating themaster communications device202 may require additional features and resources over and above those contained in themaster communications device202. In response to the operator's requirements for additional features and resources, themaster communications device202 may enter discovery mode and sends out a slavedevice request signal272 to one ormore slave devices204. In response, theslave device204 sends a slave device discoveredsignal276 that indicates whether theslave device204 is available to the operator. Themaster communications device202 receives the slave device discoveredsignal276 when themaster communications device202 is able to detect theslave device204. Themaster communications device202 may detect theslave device204 when theslave device204 comes within the detection range of themaster communications device202.
• Themaster communications device202 may also detect aslave device204 that is operating in an advertise mode. In advertise mode, theslave device204 generates a slavedevice advertiser signal274 that indicates the availability of theslave device204 to themaster communications device202. In some embodiments, theslave device204 not only advertises it availability, but also its various capabilities to themaster communications device202. In a further example, themaster communications device202 may instruct theslave device204 to enter advertise mode using either ofsignals274 or276, so that themaster communications device202 can select an appropriate slave device to meet particular operator requirements.
• Themaster communications device202 may receive anoperator request input270 that defines requirements for selecting one ormore slave devices204. For example,operator request270 may define requirements for a slave device to perform a particular function or service, and/or define the number of slave devices that will be necessary to perform a particular service.
• Using the slavedevice request signal272, themaster communications device202 may also query the resources or capabilities of theslave device204. The resources of theslave device204 may include resources that may be provided to the operator. Resources of theslave device204 may include but not limited to display dimensions, bit per pixel, aspect ratio, frame rate, audio channels, and/or the audio sampling rate.
• As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, embodiments of the masterslave communications system200 may include any quantity ofslave devices204 in addition to themaster communications device202. Further, the masterslave communications system200 may include any quantity ofmaster communications devices202 in addition to theslave device204.
A Second Exemplary Master Communications Device/Slave Device Configuration
• FIG. 3 illustrates a block diagram of a second masterslave communications system300 according to an exemplary embodiment of the invention. Themaster communications device202 may be integrated with theslave device204 to form the masterslave communications system300. Themaster communications device202 includes amemory318 and a master/slave device controller306.
• Themaster communications device202 provides functions which may include wireless communication, computing capabilities, and/or any other suitable functionality that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present invention. Themaster communications device202 may also support services relating to computing capabilities, such as Short Message Service (SMS), electronic mail, Internet access, gaming, short range wireless communications, camera, Multimedia Messaging Service (MMS) messaging, digital audio player, radio, and Global Positioning System (GPS) services and/or any other suitable service that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present invention.
• As shown inFIG. 3, the master/slave device controller306 may receive a received communications signal360 from another communications device. The master/slave device controller306 downconverts, demodulates, and/or decodes the received communications signal360 to recover information, such as one or more commands to be executed by themaster communications device202 and/or data to provide some examples, that is embedded within the receivedcommunications signal360.
• As another example, the master/slave device controller306 may provide a transmitted communications signal362 to another communications device. The master/slave device controller306 upconverts, modulates, and/or encodes information to provide the transmitted communications signal362, where exemplary information may include one or more commands that are to be executed by another communications device and/or data to provide some examples. As a further example, the master/slave device controller306 may receive the received communications signal360 from a first external communications device and provide the transmitted communications signal362 to the same first external communications device, or to a second external communications device.
• The master/slave device controller306 also processes the received communications signal360 to properly route the information, such as one or more commands and/or data, embedded within the received communications signal360 to theslave device204 asslave device data356. Further, the master/slave device controller306 may save the receivedcommunications signal360, or a processed version thereof, in thememory318 ascommunications data370.
• For example, the master/slave device controller306 may format the received communications signal360 into data frames and may perform error encoding, such as cyclic redundancy check (CRC) to provide an example, on the data frames prior to forwarding asslave device data356 orcommunications data370. The data frames may include frame delimiters to indicate a start and/or an end of each of the data frames. As a further example, the master/slave device controller306 may parse the received communications signal360 prior to generating theslave device data356 and/or thecommunications data370. The received communications signal360 may include a header of one or more bits as part of the information. The one or more bits of the header may be interpreted by the master/slave device controller306 to deter nine whether to route the received communications signal360 to theslave device204 and/or to thememory318. Further, the master/slave device controller306 may receive and formatslave device data356, for transmission as transmittedcommunication signal362. Likewise, master/slave device controller306 may retrieve and format thecommunications data370 for transmission, as transmittedcommunication signal362.
• Thememory318 reads and/or writes thecommunications data370. Thememory318 may include a data store such as a transponder, a tag, a smartcard, read only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices and/or any other suitable machine-readable medium that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention that is communicatively coupled to the master/slave device controller306.
• The master/slave device controller306 processes theoperator request input270, the slave device discoveredsignal276, and theslave device advertiser274 and determines the slave devices, such as theslave device204 that may be available to the operator through themaster communications device202. In some embodiments, the operator requires added capabilities that themaster communications device202 cannot provide alone. For example, but without limitation, a larger display may be needed to properly view information of receivedcommunications signal360. The master/slave device controller306 may route at least a portion of the information that is embedded within the received communications signal360 to theslave device204 as theslave device data356. In this example, the complement of services that is provided to the operator is split between themaster communications device202 and theslave device204. In such a case, theslave device204 serves as an extension to themaster communications device202 so that theslave device204 and themaster communications device202 serve the operator as a single interactive system.
• When operating as an output device, theslave device204 receives theslave device data356 from the master/slave device controller306, and operates as an output device for the masterslave communications system200. For example, theslave device data356 may represent data to be displayed by theslave device204 and/or one or more commands to be executed by theslave device204.
• Alternatively, theslave device204 may operate as an input device to receive information from the operator that is to be provided to the master/slave device controller306 as theslave device data356. The information from the operator may represent data from the operator and/or one or more commands to be executed by the masterslave communications system300.
• The master/slave device controller306 also monitors an available slave device resources signal352 to determine the resources of theslave device204 required and/or available to execute the requests of the operator. The slavedevice resource signal352 identifies the available resources for one ormore slave devices204. In an embodiment, the master/slave device controller306 queries theslave device204 to determine the resources available to the operator in theslave device204, in order to execute the requests of the operator. Resources requested by the master/slave device controller306 may include but are not limited to: audio channel, display area, specific frame rate, and specific aspect ratio. If the desired requirements are met, then theslave device204 grants the requested resources to the master/slave device controller306.
• The following example illustrates the engagement between themaster communications device202 and theslave device204, where the example is illustrated in the context of visual displays and resources associated with visual displays. As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, the visual displays may also have audio and touch screen capabilities without departing from the spirit and scope of the present invention. The following example applies to any type of resource related to: audio, video, visual, touch screen, and/or any other type of implementation without departing from the spirit and scope of the present invention.
• For example, the master/slave device controller306 queries the slave device(s)204 to determine the respective available resources, and in response receives the available slave device resources signal352. The master/slave device controller306 determines that the frame rate of theslave device204 is 30 frames per second, the aspect ratio is 4:3, and the bit per pixel is 4:4:4, by examining the available slave device resources signal352. The master/slave device controller306 then requests the same frame rate, the aspect ratio and the bit per pixel resources from theslave device204. Theslave device204 grants the frame rate, the aspect ratio, and the bit per pixel resources to the master/slave device controller306.
• The master/slave device controller306 processes the available slave device resources signal352 to intelligently route theslave device data356 to theslave device204. For example, the master/slave device controller306 receives the available slave device resources signal352 that identifies the frame rate of30 frames per second, the aspect ratio of 4:3, and the bit per pixel of 4:4:4 for theslave device204. As another example, the available slave device resources signal352 may identify exemplary display screen parameters of the slave device, such as 1680×1050 for a screen size. Based on these resources, the master/slave device controller306 configures themaster communications device202 and theslave device204 in order to best display information to the operator, where the configuration takes into account the resources of theslave device204. The master/slave device controller306 communicates the configuration of theslave device204 with theslave device data356.
• For example, the master/slave device controller306 sets the proper audio sampling rate, the proper bit rate, the proper display configuration, and the proper ratio for themaster communications device202 and theslave device204 so as to properly display the information to the operator. For example, themaster communications device202 may include a high definition television (HDTV) with a bit rate of 15 Mbit/s. However, the available slave device resources signal352 may include a standard definition television bit rate of 3.5 Mbit/s. Based on the bit rate of theslave device204, master/slave device controller306 may configure the display of themaster communications device202 to occur at theslave device204 bit rate of 3.5 Mbit/s rather than themaster communications device202 bit rate of 15 Mbit/s. In doing so, the information may be properly displayed to the operator on themaster communications device202 and theslave device204. The master/slave device controller306 communicates the bit rate of 3.5 Mbit/s to theslave device204 with theslave device data356.
• In another example, the master/slave device controller306 configures themaster communications device202 and theslave device204 so that themaster communications device202 and theslave device204 display the information as a single display to the operator. In such an example, the master/slave device controller306 may configure themaster communications device202 to display half of the information (e.g. half of an image). The master/slave device controller306 may also configure theslave device204 to display the other half of the information. In doing so, themaster communications device202 and theslave device204 act as a single interactive system to the operator in displaying the information. The master/slave device controller306 communicates the portion of the information to be displayed by theslave device204 with theslave device data356.
• As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, any combination of the information may be displayed on any combination of themaster communications device202 and theslave device204. Further, any quantity of master communications devices and slave devices may be incorporated without departing from the spirit and scope of the invention. For example, the master/slave device controller306 may configure themaster communications device202 andmultiple slave devices204 so that each displays fractional portions of the information, where the fractional portions assigned to the various devices may be different from each other.
Exemplary Embodiments of Master Communications Device/Slave Device Configurations
• The following exemplary embodiments illustrate the engagement between themaster communications device202 and theslave device204. The below example is illustrated in the context of visual displays and resources associated with visual displays. As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, the visual displays may also have audio, touch screen sensing capabilities, and/or any other capabilities without departing from the spirit and scope of the present invention. The following examples apply to any type of resource related to audio, video, visual, touch screen, and/or any other type of implementation without departing from the spirit and scope of the present invention.
• FIG. 4A illustrates a first exemplary master communications system according to an exemplary embodiment of this invention. Themaster communications system400 includes themaster communications device202, amaster display402, asensor408, anddisplay information404.

• Theslave device204 may be, for example, an output device to display information relating to the services provided by theslave device204 to the operator. Specifically, theslave device204 may be configured to display a portion of the data included in thedisplay information404. Accordingly, theslave device204 may be configured to display the portion of the data included in thedisplay information404 that is not displayed by themaster display402. Themaster communications device202 communicates the portion of thedisplay information404 to be displayed by themaster display402 using themaster display data458. Themaster communications device202 communicates the portion of thedisplay information404 to be displayed by theslave device204 using theslave device data356.
• Themaster display402 may be extended by attaching theslave device204 to themaster display402. By attaching theslave device204 to themaster display402, the display provided to the operator is enlarged. Instead of attachment, theslave device204 may simply be placed physically adjacent to themaster display402, as shown. Thesensor408 may be located on themaster display402 and thesensor430 may be located on theslave device402. Thesensor408 may detect theslave device204 as theslave device204 when thesensor430 comes within the detection range of thesensor408. Once theslave device204 has come within the detection range of thesensor408, themaster communications device202 may communicate thedisplay information404 to theslave device204 with theslave device data356. A method of communicating theslave device data356 may include but is not limited to: Wi-Fi, high definition multimedia interface (HDMI), and/or any type of wireless communication without departing from the spirit and scope of the present invention. The master communications device/slave configuration420 depicts the seamless and automated attachment of themaster display402 to theslave device204, where thedisplay information404 is displayed seamlessly across themaster display402 and the slave device406 in an integrated fashion.
